Overview

Since UITS has enabled virus filters for email attachments at IU, you will need to rename the file extension of blocked file types so that legitimate attachments can be delivered.

If you're sending multiple files, consider archiving them with a utility such as WinZip to prevent email providers from automatically adding them to a zip archive, and thus blocking the message. This way, you can remove or change the file extension and allow the attachments to be delivered. For more, refer to the relevant section below.

Windows

Windows has built-in support for zip files, so you can archive and unpack a file or group of files. You'll be able to email this archive as long as you rename the file extension(s) of its contents and then archive it:

1. Make sure Hide file extensions for known file types is unchecked.
2. Right-click each file and then select Rename. Change the last three letters to a file extension not blocked by the attachment filter (for example, txt), or remove the extension altogether.
3. Right-click the file or selection of files, and select Add tozip.
4. Right-click the resulting archive and select Rename. Change the last three letters to a file extension not blocked by the attachment filter (for example, txt), or remove the extension altogether.
5. Attach this file to the message, instructing the recipient to add the original file extension(s).

macOS
